My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Canon FD 300mm f/4 L on a ADM dovetail rail on the top of my optical tube. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop using my skill set and relying on the famous Astronomy Tools Action Set.
